Probably it's the same issue that arised in the closed issues #8 and #9 (caused by the YaHP library?).

I also have some dependencies to render XLS documents:

    - org.apache.poi -> poi 3.7
    - net.sf.jxls -> jxls-core 1.0-RC-2

Unfortunately, I'm currently unable to generate PDF documents.

I had the same problem while trying to use excel and pdf modules together. I found a provisional solution updating the xml-apis.jar with xml-apis-2.0.2.jar because the libraries of pdf module were older than those the excel module needs. And then I got your exact problem. This is because after updating there were some classes missed. So I had to create a new custom jar with the classes contained in "org/w3c/dom/html2/" of the old xml-apis.jar. And that's all! For the time being it's working for me.
